“Only the following items should be considered to be grave faults: not respecting another's rights; allowing oneself to be paralyzed by fear; feeling guilty; believing that one does not deserve the good or ill that happens in one's life; being a coward. We will love our enemies, but not make alliances with them. They were placed in our path in order to test our sword, and we should, out of respect for them, struggle against them. We will choose our enemies.”
- Paulo Coelho, "Like the Flowing River"
